I had an interesting request the other day: "How can I make a YouTube video play on a loop?" This was a first and after a quick Google search, I found InfiniteLooper.com. Incredibly easy to use, free, and works like a charm! Just copy and paste the YouTube video URL and click play. You can even put the video in full screen mode and it will happily play and play and play! (Please note that private or unlisted videos will not work.) Click here to try it for yourself!
